Optimizing reboot time down from 20 minutes to 1 minute is a significantly meaningful improvement; it's literally a 85% reduction in time spent during each boot process from the original time.
if reducing boot time from 20 minutes down to 1 minute, in a server environment, is a serious issue for you, maybe you should be looking at why you need to reboot so often? i'm somewhat puzzled by the fanboi mantra of "i've been running whizzy weasel and have 1574 days of uptime", which has now been supplanted by "geez, i have to wait 3 minutes every time i reboot this thing". running ntp, dhcp, dns, smtp, imap, http, that's what we do in serverland. and in addition to that, we need to run whatever the latest and greatest piece of crap that's being touted on slashdot (redis, mongo, couchbase, elasticsearch, anything that uses ruby/forever). we generally don't have alot of say in what we have to run because the fanboi's run the media, and management tends to give media more credence than the decades of experience they have in-house. that's how linux made it into the server environment in the first place. systemd sounds like a really useful thing if you are running a desktop system. as far as booting up a server, to run services, and to keep those services running, the init.d/rc.d/etc systems do a good job, and its generally not that hard to add/modify if you are half-assed competent. before criticizing people for being afraid of new technology, make sure that you yourself are not afraid of existing technology. --jim -- Jim Mercer Reptilian Research jim@reptiles.org +1 416 410-5633 "He who dies with the most toys is nonetheless dead"
